TOP-ROLL-SADDLE MEUI-IANISIVI.

Application filed October 20, 1911.

To all whom it may concern.

Be it known that I, Lnwrs T. HoUen'roN, a citizen of the United States, residing at .Vorcester, county of WVorcester, State or Massachusetts, have invented an Improvement in Top-Roll-Saddle Mechanisms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to top roll saddle mechanism and particularly to the connection between the stirrup and the weighted lever, the object of the invention being to provide a novel construction by which the point of connection between the stirrup and the weighted lever can be readily adjusted thereby to vary the relative lengths of the lever arms for the purpose of throwing a greater or less weight on the top rolls.

In top roll mechanism it is customary to provide a weighted lever which is fulcrumed at one end on a lever screw or fulcrum member and which is hung intermediate of its ends on the stirrup through which the weight is applied to the top roll saddle. In carrying out my invention I provide a stirrup-positioning member which is movably mounted on the weighted lever and which serves to position the stirrup relative to the lever, the adjustability of the positioning member on the stirrup providing means for adjusting the relative lengths of the lever arms of the lever. In the preferred embodiment of my invention this stirrup-positioning member has such a construction that the position thereof may be shifted thereby to vary the relative lengths of the lever arms without taking the weight off from the lever or without disconnecting the stir-- rup either from the lever or from the top roll saddle and without affecting appreciably the position of the weighted lever.

Referring to the drawings wherein I have shown a selected embodiment of my invention which is suflicient to disclose the principle thereof, Figure 1 is a view showing in side elevation a top roll saddle mechanism embodying the invention;

Fig. 2 is a section through the weighted lever on the line mw, Fig. 1;

of the weighted lever before the positioning member is applied thereto;

Fig. 6 is a section on the lineoa-, Fig. 2.

1 indicates the usual roller beam, 2 a stand or support rising therefrom, 3, 4 and 5 designate top rolls, and 6,7 and 8 the bottom rollswhich are journaled in the stand 2 in usual manner. The top roll saddle may have any suitable or usual construction as it forms no part of the present invention. Said saddle is herein shown as comprising the under member 9 which rests on the center and rear top rolls and the upper member 10 which rests on the front top rolls and on the under member.

The weight is applied to the top rolls through a stirrup 11 which is hung from a weight-transmitting member 12 that rests on the upper member 10 and is herein shown as connected at one end to a clip 13 that is secured to the cap rail 14. This particular form of top roll saddle construction, however, is not essential to, the invention as the improvements to be hereinafter described might be used in connection with any ordinary top roll saddle mechanism.

15 designates a weighted lever which is fulcrumed at one end to a lever screw or fulcrum member 16 carried by the roller beam 1 andfrom the other end of which is supported a weight 17 by means of a link 18 in usual manner. 'The weighted lever 15 is hung on the lower end of the stirrup 11 so that the weight 17 is transmitted through the lever and stirrup to the top roll saddle as usual in devices of this class. In the present invention the connection between the stirrup and the lever is an adjustable one which permits the point of engagement between the stirrup and lever to be adjusted toward or from the fulcrum member 16 and a stirrup-positioning member is employed for holding the stirrup in this adjusted position. As shown herein the lever 15 is provided with the slot 19 which extends at right angles to the stirrup and the stirrup 11 is formed with a laterallyprojecting finger 20 which is adapted to extend through the slot. Said finger is preferably curved at itsupper edge, as at 21, and is provided at its lower edge with a notch 22 which straddles or embraces the lower part 28 of the lever.

The advantage of making the slot 19 at right angles to the stirrup is that the adjustment of the finger 20 in the slot does not appreciably change the angle of the weighted lever.

For positioning the stirrup in the notch 19 I employ a stirrup-positioning member which is adjustable longitudinally of the lever and in a direction at right angles to the stirrup. The stirrup-positioning member herein shown is indicated at 2e and is provided with the two side pieces 25 which embrace the weighted lever and overlie the sides thereof, said side pieces each being shown as having an opening 26 therein through which the finger 20 of the stirrup extends. ()ne of the side pieces is shown as having a finger 27 extending laterally from its lower edge and occupying a notch .28 formed in the under side of the lever,

said finger and notch serving to limitthe sliding movement 0% the positioning member on the lever. Suite le means are employed for adjusting the.stirrup-positioning member on the lever and for holding it in adjusted position, and while .my invention contemplates the employment of any suit able means for this purpose, I prefer to provide construction wherein the stirruppositioning member can be adjusted on the weighted lever without removing the weight 17 from said lever and without disconnectin the stirrup from the top roll saddle. This end can be accomplished by providing an adjusting screw which cooperates wvith the stirruppositioning member and lever to control the position of said member. 7

In the embodiment herein shown the stirruppositioning member is provided with an upturned ear 29 provided with an aperture through which extends an adjusting screw that has screw-threaded engagement with a nut 31 carried by and rigid with the lever l have herein shown the stirrup-positioning member as provided with a second apertured ear 32 through which the adjusting screw also passes, said. second serving to hold the adjusting screw in proper position. The. adjusting screw'is swiveled to the ear 29 but held from longitudinal movement relative thereto. This may be accomplished in a variety of ways and in the construction shown the ear 29 is held between the head of the screw and a collar 33 formed on or applied to the adjusting screw. The nut 31 may either be termed integral with the lever 15 or may be a separate part secured thereto. One convenient way of making this device is that shown in the drawings wherein the up per edge of the lever 15 is made with a notch 35to receive the nut 31, and the latter is formed with the two legs 3% which overlie the sides of the lever 15. The lever is preferably provided with an aperture 36 and the lower ends of the legs 34: may be bent or forced into this aperture by the action of a hammer or die thereby firmly locking the nut in place.

The stirrup 11 is preferably cut away at one side, as shown at 89, so that the head of the listing screw is always accessible.

l fith this construction it will be readily seen that the adjusting screw can be turned by means of a screw-driver thereby to shift the "-ositien of the stirruppositioning memher on the lever and to vary the relative lengths of the lever arms of said lever with out emo ng the weight from the lever'or disturb lg in any way the stirrup or the top roll saddle. l ltzrthermore, because of the screw-threaded engagement between the adjusting screw and its nut avery fine and accurate adjustment of the stirrup-positioning member can be secured. Moreover, the screw thread acts a means for locking the stirruppositioning member in its ad j usted position. 7

In n anufacturing my device I prefer to carry the slot 19 as close to the notch 42 in the lever 15 which receives the fulcrum member 16, as possible, and also to form said slot sothat its upper edge at the lower end thereof and the bottom of the notch are in substantially the samehorizontal line. lhe advantage of this construction is t when the stirrup is adjusted clear to the lo er end of the slot the weight 17 will be ilied in the most advantageous manner and without danger that during any move ment of the lever the point where the stirrup engages the lever will swing over or helow the point of engagement between the lever and the fulcrum member 16. This makes it possible to place the stirrup clear at the lower end of the slot 19 and very close to the fulcrum member 16 and when the stirrup is in this position a very light ;ht 1'? is suilieient to apply the requisite t to the top roll saddle. 7 rom the above it will be seen that some R H a Mi, v at oi Lil-o amaamgcs omy piescm constructio e that the stirrup can be readily adjusted so to apply more or less weight on the roll according to the requirements of use and such adjustment can be readily effec ed while the spinning frame is in use and without the necessity of removing the wei ht from the lover or disconnecting the I up from the saddle or making any change whatever. Another advantage results from the right angular relation between the slot 19 and he stirrup, for by means of this construction the adjustmentof the stirrup in the slot can be eliected, without appreciably changing the angle of the lever. Furthermore, the construction makes it possible to secure all the desired weight on the top roll saddle by using a comparatively light weight on the lever.

l have herein shown the head of the adjusting screw 30 as inclosed in a sleeve 51 which is loosely sustained on said screw. This sleeve acts both to protect the screw from 'being accidentally turned by any object striking against the screw head, and also to guide the screw driver and hold it in the slot of the screw head when the screw isbeing adjusted.

While I have illustrated herein one embodiment 0t my invention, yet since I believe I am the first to use a stirrup-positioning member for holding the stirrup in its adjusted position relative to the lever, I desire to claim this feature broadly and to state that the invention is not limited to the construction shown.
